Answer:it the first two
Step-by-step explanation:
Answer:
234 inches
Step-by-step explanation:
Area= base x height
Height= 18 inches
Base= 13 inches
The height of a parallelogram must be perpendicular to its base, the base of this parallelogram can only be 13 inches and the height is 18 inches. Since the side lengths are not straight lines the height must be found using this method.
The height of a triangle, parallelogram and trapezoid must have a height that is perpendicular to its base. Whereas it can be found by extending the length of the base or straightening the side length that is to be the height creating a right angle.
The standard equation of a circle is (x-k)²+(y-h)²=r², (h,k) is center of the center, r is the radius.
if the given two points form the diameter, find the midpoint of this diameter, the midpoint is the center of the circle. half the distance between these two points is the radius.
you can also use the third point to find the radius, by plugging the x and y values into the equation after you find k and h.
if either two of the three points form the diameter, plug the three different sets of x and y values in the equation. you have three equations with three unknown numbers h, k and r. solve to find h, k, and r.
